improved riding-cultivator; which :sh all *be so constructed' that the" 'plows 1n ay; :be readily guided" andacontrolled, when at work, by the driver; -with his= ieet, 1311(1- may be supported" above the'ground when passing. from place; to place.'=---- I The invention consists in the construction and-combination of. parts, which will be here;

inait'terrmore'fullydescribed, and, then pointed pIa'tesM.

out-intheiclaimsw A'a're thewheels; which revolve upon th e journalswof-theshort-aXle-arms B, attached to thefun der sideof the-ends of the" axle G.

To the axle-0, near its ends; areattached the rear--ends of two bars or hounds, D, to the inner sides of the forward ends of which are pivoted, by "two pairs of'eyebolts, the bars E, the-io-rwardends-of which meet at any angle,-and which are made of such a lengththat, their forward parts may serve as a tongue,-

and their rear parts as beams'to receive the plow-standards.

. Thelbars E are connected-and held in their proper relative positions by two cross-bars, e 0 securely bolted to them.

V To'theinner sides'of the rear ends of the hounds D arepi-voted two anglelevers, F, at

- tlieirangles. The 'shortarms of the levers F project forward,'and-their ends rest against the under'sides of the"outwardly-projeoting parts of the plates G, the inner par-ts of which are bolted to the bars E, so that by operating thesaid levers Fthe rear ends of the bars E ceive' bolts f, which pass through the said levers F,to' hold them against any side move-- ment. J arethe rear and outer standards, to the forward and rearsides of the upper ends of which are-pivoted the'arms of the"U-coup- 'lings K', so that the lower ends of saidstandards J may have a free lateral movement. The coupling-plates K are pivoted at their bendsto the outer-sides of the rear ends of the .bars E, so that the lower ends of the standards J may have a free backward and forward movement; p

. 'L are'the forward and inner standards, to the upper ends of whichare secured the cap- I To the forward end of the cap-plate M is pivoted thevforward end of the plate N, upon the upper side of the rear edge of which are formed a number of notches to receive the engaging end of the lever pawl O, which is pivoted to lugs formed upon the rear part of the plate M, and which is held against the notched plate N by a spring, P, as shown in Fig. 3.

By this construction, by raising the engaging end of the pawls 0 out of the notches in the plate N, and using the said pawl as a handle, the standardsL maybe turned to adjust the plows to throw the soil toward or from their inner surfaces to fit into the right and left screw-threads cut upon the end parts of the rod R, which is swiveled to studs or brackets S attached to the bars E, and to one of its ends is attached a crank, T.

By this construction the sockets Q can turn upon the rod It to give the lower ends of the standards L a free forward and backward movement, and by turning the rod R, by means of the crank T, the standards L may be moved toward or from each other to adjust the plows to work closer to or farther from the plants, as may be desired. To therear part of each of the bars E are attached two hangers, U, in hearings in which works the rock-shaft V. The rear part of the rock-shaft V projects beyond the rear hanger U, is bent downward, and is curved upon the arc of a circle having its center in the pivot of the coupling K,and passes through a short transverse slot in the projecting end of the plate W, the inner part of which is slotted longitudinally to receive the bolt w, byiwhich it is secured to the standard J, so that by loosen: ing the said bolts w the lower ends of the standards J may be adjusted wider apart or closer together, as may be desired.

To the forward end of the rock-shaft V is rigidly attached a coupling-block, X, in the lower part of which is formed a transverse hole to receive the upper end of the rod Y. The upper part of the rod Y is bent at right angles to pass through the coupling-block X. This connection gives the lower parts of the rods Y'a frecforward and backward but no lateral movement. The lower ends of the rods Y are connected with the lower parts of the forward standards L by short connecting-rods Z, as shown in Fig. 2.

To the middle part of the rock-shaft V is rigidly attached a coupling-block, A In the outer part of the couplin gblockA is formed a hole to receive the outer end of the hori-.

zontal rod B, which is bent downward at right angles to pass through it, so that the inner ends of said rods B may have a free forward and backward movement, but cannot move vertically without turning the rock-shaft V in its bearings. To the inner ends of the rods B are attached the upper ends of two short chains, 0 the lower ends of which are attached to the treadles D To the forward ends of the treadles D are rigidly attached bars d, which project upward and incline forward, and the upper ends of which are pivoted to the inner sides of the bars E.

By this construction, by'bearing down upon either treadle, D the lower ends of the plow standards J L upon that side will be moved outward, so that the driver can guide the plows with his feet to avoid irregular bills or a to follow crooked rows.

E is a yoke or bent bar, the ends of which are pivoted to the upper parts of the inner standards D, so that the outward movement of the standards J L upon one side may give a corresponding inward movement to the standards J L upon the other side.

' The draft strain upon the outer standards J is sustained by the brace-rods F which pass through holes in the forward hangers U, and

have hooks or heads formed upon their for ward ends, which rest against thesaid hangers, and thus sustain the draft strain. The

rear ends of the brace-rods F are pivotedto the lower parts of the standards J. If desired, the brace-rods F may be made in two parts,'the ends of the one part enteringa sockv a et formed upon the end of the other part, and

being secured by a wooden pin, so that should the plow strike an obstruction the said pin may break and allow the standard to swing,

back to prevent the plow frombemg broken.

Several holes are formed in the brace-rods I1" to receive the wooden pins, sothat the pitch of the plows maybe adjusted, as required.

This construction of the rock-shaft V and the -brace-rods F allows the outer standards J to' i be swung forward, and thus raised from the ground, where they may be secured in place,

and supported away from the ground by hooks G, which hang upon the rock-shafts V, and

hook into eyes 9 attached to the said standj ards J. v The draft strain upon the inner standards L is sustained by the brace-rods H, the

rear ends of which are pivoted to eyebolts attached to the lower parts of the said stand The brace-rods H are jointed, andtheir 7 forward ends have hooks formed upon them,

ards.

and are hooked into holes in the lower ends of the bars I, the upper ends ofwhichare secured to the bars E. Several holes are formed:

in the bars I to receive the tastening-bolts to enable the pitch of the plows to be adjusted.

By this construction the forwardends of the brace-rods H may beunhookedfromthe bars l, and hooked into eyes h attached to the bars E, to support the said inner plows away from the ground,when desired. J are guard-plates,

which are placed at such a distance apart as to, straddle the row of plants, and prevent said plants from being injured or covered by the clods and soil thrown by the inner plows. The lower parts of the forward ends of the guardplates J are rounded off to enable them to pass over the ground readily. The forward ends of the plates J are attached to the forked rear end of the bar K, by which they are drawn,and at the same time held in proper relative-position. The forward end of the bar K is pivoted to the rod L at the base of the hook Z, formed upon its rear end, and is further secured by a bolt passing-through it and through one of a number of holes formed in said hook I, so that by adjusting the said bolt the forward ends of the guards may be adjusted higher or lower, as may be desired. The forward end of the rod L has a number of holes formed in it to receive the pin or bolt, by which it is secured to the roller M, pivoted to and between the bars E. The rear ends of the guard-plates J are attached to the forked lower end of the rod N, by which they are supported and held in the proper relative position. The rod N passes up through a guide-hole in the arm 0, rigidly attached to the cross-bar 6 and has a collar, P, placed upon it to rest upon the said arm 0. The collar P is secured in place by a set-screw, Q, so that it may be readily adjusted to sup port the rear ends of the guard-plates J at any desired height. To the center of the yoke E is rigidly attached a downwardly-projecting arm, R, the lower end of which is bent forward, and is slotted or forked to receive the rod N.

By this construction, as the inner standards L are moved laterally, the guard-plates J will also be moved, so as to keep the said guard-plates always midway between the said standards. To the bars E are attached guiderods S, which pass.through eyes T, attached to the forward side of the axle G, to cause the bars E to move up and down vertically when being adjusted. U is the drivers seat, which is attached to the rear ends of the bars V. The bars V rest upon the axle O, and are kept' from lateral movement upon it by being placed between pins attached to its upper side. The forward ends of the seat-bars V are connected by a short cross-bar, W, the upper side of which is rounded off, and has a pin, X, attached to its center to enter a socket, Y, attached to the center of the cross-bar 6 attached to the bars E. Z are the plow-plates, to the rear sides of which are attached bars A which are slotted longitudinally, to receive the bolts B by which they are secured to the seats or shoes 0 The end parts of the slotted bars A are bent forward to raise the bodies of said bars away from the rear sides of the plow-plates sufficiently to affordspace for the heads of the bolts B Upon the forward side of the seats 0 upon the opposite sides of the holes that receive the bolts B are formed short flanges which rest against the side edges of the bars A and thus hold the plows Z against side movement. The rear sides of the seats 0 are concaved to fit upon the rounded forward sides of the standards J L, where they are secured in place by bolts D which pass through holes in the said standards, and through a short transverse slot in the upper part of the said seat.

By this construction, by loosening the bolts B the plows Z may be moved up and down upon their seats, and by loosening the bolts D the said plows may be turned in or out to throw the soil toward or from the plants, as may be desired.

'Having thus described my invention, I claim as new and desire to secure by Letters Patent-- 1. The combination of the bent rock-shafts V, slotted adjustable plates W, stationary hangers U, inward] y-extendin g rods B, treadles D downwardly-extending rods Y, and links Z, with the inner and outer adjustable shovelstandards, and the vertically adjustable beamframe, as and for the purpose set forth.

2. The combination of the swinging and laterally-adjustable collars Q, notched plate N, cap-plate .M, pivoted catch 0, and spring P, with the inner shovel-standards L, transverse screw-shaft R, and the beam-frame, as and for the purpose set forth.

3. The combination of the roller M, adjustable front rod L, having perforated hooked rear portion Z, with the plant-fenders J, and its front arms K,as and for the purpose set forth.

4. The combination of the bent and forked bar R, with the adjustable supporting-rod N of the guard-plates J, and the yoke E, pivoted to the plow-standards L, substantially as herein shown and described.
